Diorite is an intrusive igneous rock formed by the slow cooling underground of magma with a moderate silica content and a relatively low content of alkali metals. It is intermediate in composition between low-silica mafic gabbro and high-silica felsic granite.

Diorite ( DY-ə-ryte) is an intrusive igneous rock formed by the slow cooling underground of magma (molten rock) that has a moderate content of silica and a relatively low content of alkali metals. It is intermediate in composition between low-silica (mafic) gabbro and high-silica (felsic) granite.

A separate intrusion of igneous rock, the Taft Granite, forms the uppermost portions of the cliff face. A third igneous rock, diorite, is present as dark-veined intrusions through both kinds of granite, especially prominent in the area known as the North America Wall.

Batholiths are almost always made mostly of felsic or intermediate rock types, such as granite, quartz monzonite, or diorite (see also granite dome).
